I just got a small and power efficent pc for free (eee pc 1007). I read that it uses 40 watts, and now i'm left wondering if i could run it on "natural" power like wind, sun light etc. I live in a windy city but my house is not that high, also sun shines pretty much 24/7 now that its summer. I have some scrap materials to make small wind generator and such. What do you think /diy/, what kind of power source could keep up with the pc? and yes i'm planning to keep it on 24/7
>>995704 Basically, you'll need- >UPS capable of running for 10-12hr >Rectifier to convert DC-AC which goes to the UPS >Solar Panels to Rectifier
Then you're going to need to figure out how many amps it draws and how many you can put back into the UPS as well as losses from the system itself. Wind-generators are pretty fucking useless things really, solar's semi-dependable but you're going to need... Comment too long. Click here to view the full text.

Well.. okay? That's overcomplicating things a bit, especially in the DC-AC rectifier bit.
Basically you'd be going DC -> AC -> DC -> AC for no reason. Now, sticking with the UPS plan, you could just buy a charge controller and hook it up directly to the UPS battery or better... Comment too long. Click here to view the full text.
Hey /DIY/, I got a pair of first edition Marshall Majors that need some repair. I've found where the wire broke in the cord and bought a new TRRS plug to replace the ungodly sealed one it came with. Trouble is, the original plug was a full plastic mold with the wires inside, so I couldn't figure out which wires went where.
I've a standard TRRS plug, vut the wires are like this:
Blueish-green wire Copper/gold with with fiber Copper/gold wire Red wire in insulation sleeve Reddish wire
Sorry if vague, I'll take a picture afterwards,... Comment too long. Click here to view the full text.
I want to prank a relative that got me good last month. He left a Bluetooth speaker in the bathroom that recorded me singing in the shower and having a fat ogre shit in the toilet, then sent it to my coworkers & friends.
I want to get him back by making a retractable clown that explodes foward when he opens the bathroom door scaring him, but that's not it. It will also have a taser attached(on low) that will also shock him for double shock value(or pepper spray, still debatin). It will all be on video as well.
Just want to get him back without being weird. Thoughts?
>>995413 If you're actually being serious, the tazer is a fucking stupid idea and could potentially kill someone. Pepper spray, likewise, is fucking fucking retarded. Not only is it taking shit too far, but it will fuck over anyone who goes near the bathroom for several hours.
If a resin is "non-toxic when cured" do you think it would be safe to cast hamster tubes with, even if not "food-grade"? The hamster will be walking on it and licking his paws. I am considering Polycraft FC6620 Fast-Set Water Clear Polyurethane: http://www.ebay.co.uk/itm/321456950653?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT Or an epoxy resin: http://www.ebay.co.uk/itm/331836430786?euid=42e9abbdbb064a6dbd38e603135c1afd&cp=1
>>995204 From what I understand about food grade plastic, its more about breaking down when in contact with food or leaching something not so great into food. That or it holding onto germs and letting them fester if its a reusable plastic cup or something.
I mean it does say non toxic on it, and its not like you are making a water bowl out of it.

I'm looking to purchase a vinyl cutter and am wanting to know if these ebay cutters are as bad as everybody says. Of course people with Roland cutters will say they're shit, but i won't be using it on a commercial level.
>>995113 >It cant actually be that hard for a specific built printer like in the OP to say cut out some letters and shit.
dunno fug about them either, but, I'd dispute that greatly, for a start.. its got to drag a cutting edge around with great accuracy, at exactly the right depth, etc. - the potential for it fucking up, jamming or catching is greatly increased over say, a normal printer. And as we all know, they never fuck up..
These things are, what, $200 new, Rolands, $2k? -... Comment too long. Click here to view the full text.
>>995143 Im experienced in the cheap chinese 3d printers, and the sheer accuracy and plotting ability of these cheap low priced stepper controlled machines is actually amazing. Much more so than you would think.
The cheap vinyl cutter in the OP looks to use the same GT2 timing belts and steppers, and I would assume the same general stepper controllers. Its all really cheap chinese shit, but it performs so much better than the price would project.
The knife cutting system is very basic looking aswell, Its not as... Comment too long. Click here to view the full text.
First time poster here, long time lurker. Basically I own some shitty hilly junk land. I wanna put some storage in it but it's all hill. I'm semi inexperienced with diy so I'm probably being retarded here. But I want to put a storage shed in this land, in being the key word, I wanna build a small subterranean storage shed, maybe 6ft by 6ft into a hill. I understand the critiques towards underground building with moisture and maintenance etc but I don't plan to live there any time soon so as far as I can see from practical obstacles it's just...

I don’t know much about electronics, but I’m curious. When a board like this (PSU for an LED tile) won’t supply power, what are generally the things to look at/for? I know I’m not showing the traces, so you’ll probably make fun of me, but I’m kind of just curious as to what is (statistically) most likely the problem since this seems to happen so frequently. Bad transformer?
Just found out this site called Inventables, seemed like a dream come true for a casual maker. Woodworking materials for super reasonable prices and not bound by "9001 pieces minimum order" rules. Alas, while African Mahogany for 10 bucks a piece is a really good offer, 40 dollars for shipping to Sweden is out of the question. Do similar marketplaces exist inside EU? I live in a small shitty town and I'd rather order online.
I want to buy an air compressor to learn how to paint my car myself, but why do some compressors have small tanks like this? They don't have those big 30 gallon tanks yet they're just as expensive and can cost $300 used or more, so what can they be used for?
Wheel barrow type compressors are meant for rough construction sites as they are a little easier to move around, and are meant to run 3 maybe 4 framing/roofing nailers at the same time. They are not continuous duty though...
A continuous duty comp with a larger tank, higher cfm are necessary for orbital sanders, drills and paint guns...
Don't know about the electric ones but gas are usually like that because they put out enough air to not need a large tank. Assuming electric ones built like that are just for the sake of being more portable but no reason they should cost what they do
Related and I don't know /diy/s culture enough to know if it merrits it's own thread.
I'm going to paint an xbox one controller and some auto paint is beautiful so I'm going to use it if I can. What tool would I need to spray the powder? Is it mixed during spraying or before? (If before that broadens my application options. Would a stensiling sprayer work?
Is it possible to rewire sata cable into usb so i wouldn't have to buy adapter. If so can 2.5 5400rpm hdd run with the power provided by the usb to sata cable or will i have to use external power supply. pic kinda related
